hicpp-exception-baseclass

=========================
|
||
|
|
||
|
Ensure that every value that in a ``throw`` expression is an instance of
|
||
|
``std::exception``.
|
||
|
|
||
|
This enforces `rule 15.1 <https://www.perforce.com/resources/qac/high-integrity-cpp-coding-standard-exception-handling>`_
|
||
|
of the High Integrity C++ Coding Standard.
